Adopt said structure, the velocity mode of feeding grinder is single, and the hommization operability is low, and the precision of grinding machine is generally the highest only to reach 0.005mm.
The utility model content
In order to remedy the deficiencies in the prior art, the utility model provides a kind of special-purpose variable-speed feeding speed device of grinding machine that can be shifted, at least comprise correct grinding shelves, corase grind shelves and neutral gear totally three shelves, both improved the precision of grinding machine greatly, once added its hommization operability again.
For achieving the above object, the scheme that the utility model adopted is:
The special-purpose variable-speed feeding speed device of grinding machine, comprise handwheel, power transmission shaft, bevel gear and speed change gear, handwheel is installed on the driving shaft of speed change gear, power transmission shaft one end is connected with the output shaft of speed change gear, the other end is connected with bevel gear, also is provided with the gearshift that has correct grinding shelves, corase grind shelves and neutral gear three-step gear shift gear at least on the speed change gear.
As improvement of the technical scheme, gearshift comprises gear change hand lever, handle axis of rotation, poke rod chaining part and poke rod, poke rod is fixed in poke rod chaining part one end and is connected with speed change gear, the poke rod chaining part other end is connected with handle axis of rotation, and gear change hand lever then is fixed on handle axis of rotation one side.
As improvement of the technical scheme, speed change gear comprises change gear box, is provided with gear one, gear two, gear three and the gear four of axially parallel in the change gear box, also is provided with splined shaft, spacing axle sleeve and connector; Splined shaft is connected with handwheel is coaxial as the driving shaft of speed change gear, and gear one, gear two are coaxial affixed and be sheathed on the splined shaft; Connector is connected with power transmission shaft is coaxial as the output shaft of speed change gear, keeps holding the spacing of gear one, gear two and coaxial affixed between gear three and the gear four, and the other end of gear three then is connected by spacing axle sleeve and connector are coaxial; The flank of tooth of gear one is provided with the groove that engages with poke rod, and gear one, gear two can slide up and down and keep respectively gear one and gear four engagements or gear two to mesh with gear three under to the promotion of groove or gear one, gear two are still between gear three and the gear four at poke rod along splined shaft.
Therefore,, correct grinding shelves, corase grind shelves and neutral gear three-step gear shift can be realized,, the velocity mode of multiple feeding grinder can be realized by the output that gearshift switches speed change gear by setting the diameter of gear one, gear two, gear three and gear four:
The amount of feeding is few when being in the correct grinding shelves, and precision can reach 0.001mm, therefore can easyly guarantee at the following grinding work-piece of 0.002mm tolerance; The amount of feeding is big when being in the corase grind shelves, and precision is about 0.01mm, can be used for realizing rapid processing, also can with correct grinding shelves stationary knife and processing, save the operating time more earlier with the fast feed of corase grind shelves; Can not realize feeding when being in neutral gear, the rotation of handwheel does not pass to power transmission shaft, can avoid processing to suspend or in have no progeny and change the error that causes the workpiece processing capacity because of the other turned position of handwheel.
Compare with prior art, the beneficial effects of the utility model are: by the output of gearshift adjusting speed change gear, realized the speed-change and gearshift of feeding grinder, improved the grinding machine precision, strengthened its hommization operability.
